Question

I know it’s simple question, but I have tried so many approaches, in all of them I lose data, text data, not those trailing 0’s after each byte.

I converted CString to wchar_t using GetBuffer(0), still no luck. I can’t get a proper LPBYTE.

At end I need it to be const LPBYTE, but I think with a simple casting of LPBYTE I can get const LPBYTE.

So could you help me to convert CString or wchar_t to LPBYTE array?

Thanks

If you want to “see” the content of a CString as a simple “raw” sequence (array) of BYTE‘s, you can use CString::GetString() method to get the pointer to the first CString character, and then cast to const BYTE*:

CString str;
....
const BYTE* pb = reinterpret_cast<const BYTE*>(str.GetString());

If you want to “see” a single wchar_t as a sequence of BYTE‘s, you can take its address and again cast to const BYTE*:

wchar_t wch;
....
const BYTE* pb = reinterpret_cast<const BYTE*>(&wch);

But if you want to convert from Unicode UTF-16 to another encoding like UTF-8, you may want to use some conversion helpers like CW2A:

CString strUtf16; // Assume UNICODE builds (the default since VS2005)
....
// Convert from UTF-16 to UTF-8
CW2A strUtf8( strUtf16, CP_UTF8 );

// Convert (cast) to const BYTE*
const BYTE* pb = reinterpret_cast<const BYTE*>( static_cast<const char*>(strUtf8) );
